How do I automatically calculate dollars earned with time worked?

[Guest]

I calculate hours worked by subtracting Stop time from Start time givng me
hours, minutes worked. For example, hours worked 5:25. I use this to
multiply by a fixed dollar amount like $7.50. The product is not correct.
What am I doing wrong? Using Excel Office 2003.

5:25 is really 0.225694444 since time is really a fraction of a 24 hour day.

If 5:25 is in A1 then =A1*7.5*24 should give you want you want.

Thannk you. I see where the o.225 comes from but where did the 7.5 come in?
I'd like to understand this, not just apply it.

The 7.5 is the hourly rate ($7.50) as in your original post.
